Automatic Transmission

727

The most legendary Torqueflite model is the A-727, which replaced the A-488 in 1962. Assigned to the most muscular engines, heavy duty applications, and trucks, the A-727 used an aluminum case (rather than the A-488's cast iron case), saving about 60 pounds; in some models, it used a pawl (lock) for parking, actuated by a lever (1962-64 models) or by putting the transmission into Park. The first generation of iron TorqueFlites had a rear pump as well as a front pump, allowing the automatic-equipped cars to be push started. It probably wasn't officially endorsed, but it worked in emergencies, and many people knew about it (C. Paul Kozoriz.) For 1966, the rear pump was eliminated because the push-starting capability was rarely used.
